    It works

    It really does a good job of keeping her cool. I don’t know why I waited so long.

    Summer Must Have

    I have a 6 year old pit bull mix who cannot stand the summer heat in Georgia! This addition to his harness collection has already helped tremendously in the afternoons. I could tell throughout our walks that he is staying much cooler than normal. I would highly recommend this to anyone whose pup needs some additional heat protection in the warmer months.

    Helps our frenchie

    Our frenchie gets really hot on walks quickly, and this harness is helping him stay cool and go for longer walks during the summer. The sizing runs a bit larger than other extra smalls (we also have the basic harness from ruffwear, so I’m using that as comparison). It’s just a bit expensive imo.
